A High Capacity Reversible Watermarking Scheme Based on the H.264/AVC Intra Prediction and Block Classification
In this paper, we propose a very high capacityreversible watermarking scheme based on the H.264/AVC intra prediction and block classification. By decorrelating images using the intra prediction of H.264/AVC and generalizing the typical difference expansion algorithm and histogram shifting technique, we can increase capacity substantially. And by classifying blocks according to pixel shiftability and sending a classification flag into each block, the proposed scheme does not need the typical location map. Experimental results show that the proposed algorithm achieves capacity up to 2.36bpp for single embedding. (Abstract)
